The optimal solar panel tilt angle equals your latitude, facing true south (Northern Hemisphere) or true north (Southern Hemisphere). At 40° latitude (New York), set panels to 40° tilt.
The optimal solar panel tilt angle equals your latitude for year-round efficiency. This simple adjustment can increase solar output by 10 to 25 percent depending on your.
A solar panel generates its highest power output when the sun's rays are incident at a 90-degree angle to the module's surface. This condition, known as a normal angle of incidence, ensures that the maximum density of solar radiation flux is absorbed by the panel's active area.
Optimizing your solar panel angle is essential for maximizing energy production. Start by understanding tilt basics and determining your latitude. Make seasonal adjustments, tilting panels flatter in summer and steeper in winter.

The 30-degree rule is flexible: While 30 degrees is often cited as optimal, any roof pitch between 15-45 degrees will deliver excellent solar performance, typically within 5-10% of peak efficiency. Don't let imperfect pitch discourage you from going solar.
